The Service Manager at my local Honda shop said that I was lucky that my VIN was within range. That way my update was all covered under the normal Honda warranty; otehrwise, he said I might have had to pay for it. He did say that under Honda guidelines, any and all complications with ur car may be brought up with the Service Manager and if they see fit, it may still be covered under Honda warranty.
6spdChick, if u discuss it before hand with ur SM u may be able to sweettalk him into some free service.
I received the Honda ECU update about one week ago, and I'm still having small problems with the 1st gear bucking, but nothing too noticable...But, I have noticed that my car drives even smoother than it did before.
This update won't solve all ur problems, but it'll help.
